TOOL FOR CUTTING SEATS'IN RAILWAY SLEEPERS.

To all whom it may concern:

Be it known that I, ALBERT CoLLE'r, a citizen of the Republic of France,residing in Paris, France, have invented certain new and usefulImprovements in Tools for Cutting Seats in Railway-Ties and the Like, ofwhich the following is a specification.

This invention relates to certain improvements in wood workingtools ormachines, and more particularly in that class of such machines which areespecially designed and adapted for routing, so as to be capable ofemployment for forming gains. or seats in wooden railway ties orsleepers for the reception of the rails or rail-chairs, and theobject ofthe invention is to provide a tool of this general character of a simpleand comparatively inexpensive construction, having a novel and improvedarrangement of cutters whereby such gains or seats may be produced inthe railway ties or sleepers without the employment of saw-kerfs such asare usually cut in the ties or sleepers for limiting the lateral extentof the gains or seats and which, by reason of being extended deeper thanthe gains or seats form grooves wherein moisture is apt to be caught andretained in such a manner as to cause decay of the wood.

The invention consists in certain novel featuresof the construction, andcombina tions and arrangements of the several parts of the improvedcutting tool, whereby certain important advantages are attained, and thedevice is rendered simpler, less expensive and otherwise better adaptedand more con venient for use, all as will be hereinafter fully setforth.

The novel features ofthe invention will be carefully defined in theclaims.

In the accompanying drawings which serve to illustrate myinvention-Figure 1 is a view showing the improved 5 tool in sideelevation, andpartly in section at the left-hand side of the figure;Fig. 2 is a plan view ofthe improved tool; Fig. 3 is an enlarged detailview showing one of the lower cutters detached and in side elevation;Fig. 4 is a frag mentary sectional view showing the means for holdingthe lower cutters in position upon the cutter head, and-Fig. 5 is asectional view taken horizontally through the improved tool in a planebetween the upper and lower cutter heads, and showing t e lower cutterhead enlargedandinplan.

As shown in these views, the improved tool comprises upper and lowercutter heads:

the upper cutter-head, but'it'is evident that the number of such cuttersemployed may be varied without departure from the invention.

The cutters B as herein shown are so mounted upon the holders 6 thattheir axes are slightly inclined with respect to the axis of the shaft 0so as to insure a free penetrating cut at the cutting edges 0, c.

The lower cutter head A is in disk-like form and its under surface isprovidedwith a plurality of curved grooves or channels a, directed fromits central portion toward its periphery as shown in dotted lines inFig. 5, the outer ends of said grooves or channels a, being 0 on at theperiphery of the said lower cutter ead A The said grooves or channels a,a are adapted to receive a series of lower cutters B B each of whichcomprisesa flattened body portion, curved 'in the direction of itslength and having its upper edge portion adapted to be received in oneofthe said grooves or channels a as clearly shown in Fig. 4 of thedrawings. By this arrangement, the flattened knives or cutters B of thelower cutter'head are caused to extend in substantially radialdirections, and

are capable of beingadjusted endwise along thegrooves or channels a inthe cutter head: so as to permit of compensating for wear of their outerends which, as herein shown, project beyond the erifheral surfaces ofthe saidlower cutter iea Each of the lower knife-like cutters B isprovided with a reinforcing web 6 centrally extended along itsrearsurface, and adapted to fit flush u on the underside of the cutter headA, as 0 early shown in Fig. 4, and for holding the said lower cutters inposition upon said. lower cutter head I provide bolts d, d the lowerends of which have clamping lugs g, g, engaged below the webs of therespective cutters, as shown in Fig. 4, the up-- perends of said bolts:being extended up through the cutter head A and being rovided withscrew-threads so as to adapt tl ieni to receive nuts f, f. Uponloosening the bolts, the said lower cutters may be adjusted endwise inthe grooves or channels a, a for taking up wear at their outer ends, andwhen the nuts are tightened upon the bolts, the cutters are securelyclamped and held in adjusted position.

The proportions of the arts of the improved cutting tool are suc thatthe upper cutters B, B, cut through a stroke of greater radius than thelower cutters B B whereby it will be seen that in the use of theimproved tools for cutting seats or gains in railway ties or sleepers,the said upper cutters serve to smooth and remove the surfaceinequalities and roughness of the ties or sleepers at each side of theseat or gain roduced by the lower cutters B as clearly shown at h, h, inFigs. 1 and 2. In this way it will be seen that the said uppercutters'serve to produce smooth surfaces along each side of the gain orseat wherein the spikes or other fastenings commonly employed forholding the rail in posi tion upon the ties may be set and driven, sothat their heads may be engaged with the flanges at the base or foot ofthe rail seated in the gain or seat produced by the lower cutters B Inthe accom anying drawings the shaft 0 is shown as slig tly inclined tothe vertical, so as to adapt the seat or gain produced by the lowercutters B B to receive the inclined base or foot of what is known as theVignole rail, but this is in no sense essential to the presentinvention. In the drawings the arrow at 9: indicates the direction ofrotation of the improved tool.

In the use of the improved tool, the same may be fed up to the tie T insuch a manner as to produce a transverse cut of the full depth desiredfor the seat or gain across the top of the tie, after which the feedingmovement will be reversed and the tool shifted in the direction of thelength of the tie so as to produce a second cut parallel with the first.Ordinarily the cutters will have an effective diameter sufficient toproduce a gain or seat of the desired width at two cuts, but this is notessential to the invention.

Cutting tools of this general character may be used in connection withvarious machines arranged to receive them and to impart to them thenecessary movements in order that the tools may produce upon thesurfaces of the ties or slee ers suitable seats or gains to receivetherails or the chairs which carry such rails.

As shown in the drawings, the inclinations of the axes of the disk-likecutters B, B are such with respect to the direction of rotationindicated by the arrow as that the forward cutting edge 0 of each cutteris depressed below the plane of the rearmost cutting edge of suchcutter, whereby it will be seen that the rearmost cutters are maintainedout of contact with the wood and are thereby protected from wear. Bythis arrangement when the forward cutting edges of the disk- I likecutters shall have become dulled or worn, the cutters may be removedfrom the holders b and reversed so as to present what were formerlytheir rearmost cutters in position to engage the ties.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:
